Here are the hex values but I'm struggling to find how to set these values with kix:

[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\MailSettings]

"ComposeFontSimple"=hex:3c,00,00,00,0f,00,00,e8,00,00,00,40,f0,00,00,00,4e,0d,\
73,74,00,00,00,00,00,20,41,72,69,61,6c,00,00,00,00,00,00,00,00,00,00,00,00,\
00,01,00,00,00,84,ea,13,00,01,00,00,00,01,00,00,00
"ReplyFontSimple"=hex:3c,00,00,00,0f,00,00,e8,00,00,00,00,f0,00,00,00,4e,0d,73,\
74,00,00,ff,00,00,20,41,72,69,61,6c,00,00,00,00,00,00,00,00,00,00,00,00,00,\
01,00,00,00,84,ea,13,00,01,00,00,00,01,00,00,00
"TextFontSimple"=hex:3c,00,00,00,0f,00,00,e8,00,00,00,40,f0,00,00,00,4e,0d,73,\
74,00,00,00,00,00,30,43,6f,75,72,69,65,72,20,4e,65,77,00,00,00,00,00,00,00,\
01,00,00,00,84,ea,13,00,01,00,00,00,01,00,00,00

Any help would be much appreciated.
